Ulquiorra’s jjk verse could be that he's a special grade curse born from the feelings of emptiness and void. souls of people who have been consumed by the void are the primary source of his energy. I'm assuming all the espada are special grade curses just like how they are the highest rank in their own verse. Anyways, will also be assuming that in this verse Aizen is still a drop out and recruits him along the other curses. this is not the main verse but a war that took place decades or hundreds of years before the main events, so somewhere between heian and modern day. His state in present jjk-verse is a dormant curse that has been affixed to a sword, just like his other 9 "comrades" and are kept in the hidden inventory at hq.
Bruce Wayne attends a Gala. A previous Employee hijacks the event with goons
Bruce has hit the panic button. He came alone cause he got in an argument with some of them and the rest are busy.
Dick and Damian are rushing to the event. With others following suit when they can.
Hijacker asks if he has any last words.
He pulls out his pocket watch. Looks at it and smiles. Then he stares down the employee. Looks him in the eyes, knowing he can’t fight back just because of how many hired guns there are. They said if he tries to others will be shot. He dies or his kids arrive. Either or.
The guy raises his gun and fires while the others are five minutes out.
They arrive. The hijackers and goons are gone. Bruce Wayne is dead and cops are on the way
Later after his body had been processed Gordon returns the watch to Dick. He opens it and it’s a picture of everyone.
He wanted to see his kids one last time before he joined his parents
